Case Study: 17-4PH Stainless Steel Shoulder Bolt

Case Study: 17-4PH Stainless Steel Shoulder Bolt

Wind turbines are a great source of clean, renewable energy. But capturing the power of the wind requires equipment that can stand up to all kinds of weather…and wind. So when a customer needed 17-4 PH stainless steel shoulder bolts for a wind turbine, they turned to Earnest Engineering & Manufacturing. 17-4 PH is a chromium-nickel grade of stainless that offers good corrosion resistance in operating temperatures up to 600ºF. Because of its hardness, it tends to chip and “work harden” as material is removed in the machining process. Fortunately, the experts at Earnest Machine are used to sourcing and machining exotic materials on a daily basis. Our Engineers were able to work from the customer’s drawing to create the parts within the customer’s specifications and timeline.

Specifications: 17-4 PH Stainless Steel Shoulder Bolt created from 3” round stock. Shank was held to a .001 total tolerance on diameter with a surface finish of 32 microns.
